Populating Dimm Sockets - HP Pro 3400 Maintenance And Service Manual

Populating DIMM Sockets

Populate the DIMM sockets in the following order: XMM1, XMM2 or Channel A, Channel B.
Figure 7-3
Table 7-1 DIMM Sockets
Description
XMM1 socket, Channel A
(populate first)
XMM2 socket, Channel A
NOTE: A memory module must occupy the XMM1/Channel A socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●
The system will operate in single channel mode if the DIMM sockets are populated in one
channel only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity
of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B.
The technology and device width can vary between the channels. For example, if Channel A is
populated with one 1-GB DIMM and Channel B is populated with one 2-GB DIMM, the system
will operate in dual channel mode.
